Description

Technical Field

[0001] The present invention relates to the field of kitchen and bathroom, and particularly to a faucet control box. Background Art

[0002] With the improvement of people's living standards, the requirements for daily disinfection are gradually increasing, demanding high-efficiency, environmentally friendly, and residue-free disinfection effects. Ozone is widely used in various disinfection fields because it can purify air, sterilize, and disinfect, and has excellent disinfection performance.

[0003] In public places, families, hospitals and other places, when performing tasks such as handwashing, cleaning fruits and vegetables, and devices, the water flow from the faucet is required. Therefore, using the ozone water flowing out of the faucet for disinfection in the above-mentioned places can greatly meet the different usage needs of users. Currently, faucets that can produce ozone water generally use an ozone water generating device to generate ozone water. The ozone water generating device can mix water flow with ozone to generate ozone water, and the generated ozone water then flows out through the ozone water path via the water outlet of the faucet. The ozone water generating device is generally arranged under the faucet tabletop.

[0004] For the existing induction faucets with induction control functions, they need to cooperate with solenoid valves to achieve the on-off control of the water path. The solenoid valves of the induction faucets are arranged in the induction control box, and the induction control box is arranged under the faucet tabletop.

[0005] For the existing faucets to achieve both the output of ozone water and the induction control function, it is necessary to set up an ozone water generating device and an induction control box at the same time, resulting in a relatively messy overall structure of the faucet. Moreover, due to the limited installation space under the faucet tabletop, it is difficult to set up an ozone water generating device and an induction control box under the faucet tabletop at the same time. Summary of the Invention

[0006] The purpose of the present invention is to provide a faucet control box that can both output ozone water and achieve the on-off control of the water path.

[0011] A groove is provided on the end face of the outer end of the manual opening and closing member.

[0012] The ozone water generating device includes a jet injector having a water inlet, a water outlet, and an air inlet, and an ozone generator for generating ozone; the jet injector and the ozone generator are fitted in the box body, and the air outlet end of the ozone generator is connected to the air inlet of the jet injector; the water inlet of the jet injector is the water inlet end of the ozone water generating device, and the water outlet of the jet injector is the water outlet end of the ozone water generating device.

[0013] A one-way valve is connected in series between the air outlet end of the ozone generator and the air inlet of the jet injector. The one-way valve is used to control the one-way conduction from the air outlet end of the ozone generator to the air inlet of the jet injector.

[0014] The box body is provided with a ventilation port; the air inlet end of the ozone generator is connected to the ventilation port through an air inlet pipe; an installation hole is formed in the side wall of the air inlet pipe, and a gas flow sensor for controlling the operation of the ozone generator is fitted in the installation hole.

[0036] fitted Figure 1 、 Figure 3 and Figure 4As shown, the ozone water generating device 3 includes an ejector 31 having a water inlet 3111, a water outlet 3112 and an air inlet 3113, and an ozone generator 32 for generating ozone. The ejector 31 and the ozone generator 32 are cooperated in the box body 1, and the air outlet end of the ozone generator 32 is connected to the air inlet 3113 of the ejector 31. The water inlet 3111 of the ejector 31 is the water inlet end of the ozone water generating device 3, and the water outlet 3112 of the ejector 31 is the water outlet end of the ozone water generating device 3. When the water flowing in from the second water inlet joint 13 enters the ejector 31, a negative pressure is generated inside the ejector 31 to suck the ozone generated by the ozone generator 32 into the ejector 31. The ozone sucked into the ejector 31 is mixed with the water flowing into the ejector 31 to form ozone water. The ozone water is then output from the water outlet of the ejector 31, and the ozone water output by the ejector 31 is finally output outside the box body 1 from the second water outlet joint 14.

[0037] cooperated Figure 4 As shown, the ejector 31 may include a body 311 and a nozzle 312. The body 311 may be connected to the box seat 102 of the box body 1 by screwing or clamping. The body 311 is sequentially provided with a water inlet 3111, a mixing chamber 3114, a water outlet passage 3115 and a water outlet 3112 along its axial direction. The air inlet 3113 of the ejector 3 is opened on the side wall of the body 31, and the air inlet 3113 communicates with the mixing chamber 3114. The aperture of the mixing chamber 3114 may be larger than the aperture of the water outlet passage 3115. The nozzle 312 is inserted into the water inlet 3111 and the mixing chamber 3114. A nozzle opening 3121 with a gradually decreasing aperture is formed in the nozzle 312. The nozzle opening 3121 communicates the water inlet 3111 and the mixing water chamber 3114 and the nozzle opening 3121 faces the water outlet passage 3115. When water enters the water inlet 3111, the water is accelerated through the nozzle 312 and then injected into the mixing chamber 3114. The accelerated water causes a negative pressure to be generated in the mixing chamber 3114, so that the ozone generated by the ozone generator 32 is sucked into the mixing chamber 3114 through the air inlet 3113, so that the ozone is mixed with the water to form ozone water, and the ozone water is then output through the water outlet passage 3115 and the water outlet 3112.

[0038] cooperated Figure 3 and Figure 4As shown, a one-way valve 33 can be connected in series between the air outlet end of the ozone generator 32 and the air inlet 3113 of the ejector 31. The one-way valve 33 is used to control the one-way conduction from the air outlet end of the ozone generator 32 to the air inlet 3113 of the ejector 31. In the present invention, the one-way valve 33 can prevent the water flow in the ejector 31 from flowing back into the ozone generator 32 and causing damage to the ozone generator 32. Both ends of the one-way valve 33 are respectively connected to the air outlet end of the ozone generator 32 and the air inlet 3113 of the ejector 31 through a first air pipe 34 and a second air pipe 35.

An installation hole 361 is formed in the side wall of the air inlet pipe 36, and a gas flow sensor 37 for controlling whether the ozone generator 32 works or not is fitted in the installation hole 361. The gas flow sensor 37 can sense whether there is gas flow inside the air inlet pipe 36, and the gas flow sensor 37 can adopt a microphone head; when water enters the ejector 31 and generates negative pressure, external air enters the ozone generator 32 through the ventilation port 17 and the air inlet pipe 36. At this time, the gas flow sensor 37 senses that there is gas flow inside the air inlet pipe 36 and controls the ozone generator 32 to work. The ozone generator 32 works to make the air entering the ozone generator 32 react to generate ozone, and the generated ozone is then input into the ejector 31. In this way, as long as water enters the ejector 31, the ozone generator 32 will automatically work, which is convenient for people to use.
